McNeil spokeswoman Bonnie Jacobs told Consumer Ally about 34,000 bottles of Tylenol 8-Hour Extended Release Caplets in the 150-count bottles were recalled after McNeil received a small number of complaints about a musty or moldy odor. The odor is thought to come from minute amounts of chemicals from wood pallets used to store and transport the medicine -- a problem that has prompted round after round of recalls over more than a year.Included in the recall is lot number ADM074 with the UPC code of 300450297181. The lot number can be found on the side of the bottle label. Consumers who have the recalled pain medication should not use it, and should call McNeil at (888) 222-6036 weekdays between 8 a.m. and 8 p.m. Eastern Time.

In a statement on its Tylenol site, McNeil apologized to consumers about the availability of its products and offered a $1 off coupon. Its site also has a searchable product locator.

"You may have noticed that some of our Adult Tylenol products have been hard to find on store shelves due to our recent recalls," the company said. "We apologize for the inconvenience this may be causing you and assure you we are working diligently to get your products back as quickly as possible."

In a separate move on the wholesale level, McNeil also recalled 10 lots -- 717,000 bottles -- of Tylenol 8 Hour, Tylenol Arthritis Pain, Benadryl, Sudafed PE, Sinutab and Tylenol cold medicines after a review of production records at its closed Fort Washington plant showed times when manufacturing equipment either wasn't properly cleaned nor adequate documentation kept. The company said the move was a "precautionary measure" and it was unlikely quality was affected.

McNeil lists the lot numbers affected by the recall -- an expansion of an earlier announcement in January. The company said consumers can continue to use those products and don't have to do anything for the recalls.
